Patent attributes
A projector includes a cooler configured to cool a cooling target based on transformation of a refrigerant into a gas. A refrigerant generator of the cooler includes a first blower configured to deliver air to a first portion of a moisture absorbing/discharging member, a first heat exchanger, a heater, a second blower, a circulation path along which the air exhausted from the second blower circulates, and a second heat exchanger provided in the circulation path. The circulation path has a first path along which air after passing through a second portion of the moisture absorbing/discharging member flows into the first heat exchanger and a second path along which air exhausted from the first heat exchanger is delivered to the second portion. The second heat exchanger exchanges heat between the air flowing along the first path and the air flowing along the second path.
